Posture problems are rampant, especially among those of us who work hunched over our keyboards all day. If you're not sure if your posture needs fixing or are sure and want some help, this guide from Men's Health is for you.

The first step is to analyze your alignment by having a friend take a full-body photo of you (with your shorts on) from the front and from the side. Then compare against the 7 points in the illustration above.

For each area, Men's Health offers simple exercises you can do to correct the problem. For example, if you have "forward head" (you carry your head too far forward):

The problem: Stiff muscles in the back of your neckFix it: Stretch with head nods daily: Moving only your head, drop your chin down and in toward your neck while stretching the back of your neck. Hold for a 5 count; do this 10 times.

The problem: Weak front neck musclesFix it: Do this neck "crunch" every day: Lying faceup on the floor, lift your head so it just clears the floor. Raise your head, and hold for 5 seconds; do 2 or 3 sets of 12 reps daily.
